The best description that fits a whale shark is a mouthful of teeth and constantly hungry stomach. Yes, it may seem morbidly appropriate yet it is not the truth. The fact is that, compared to other shark species, the whale sharks are far different.
The Whale Sharks are actually viewed as filter-feeders. They chiefly feed on plankton, krill, macro-algae, small nektonic vertebrates, small fishes and squids. A unique oral anatomy is possesed by the whale sharks which enables it to filter for food, gulp in the water and expulse water through its gills.
Unlike other sharks, the whale sharks don't have big sharp teeth. In actual fact, the size of their teeth is somewhat smaller seeing that their teeth provide no real use as part of feeding. To paraphrase, whale sharks never munch their food. As filter-feeders, these mentioned whale sharks possess a unique raking mechanism attached in their gills which serves to filter food from the water they gulp in. Their filter-feeding characteristics makes their diet interesting, odd but logic.
Filter-feeding
In lieu of preying on fishes, a whale shark sucks in mouthfuls of water abundant with macro-algae, tiny fishes and plankton. And then, it closes its mouth to catch the water inside of the body, which happens to be funneled through the gill flaps, where water is removed. Almost all of the food particles are stuck against the dermal denticles lining the whale shark's pharynx and also gill plates. They use their fine sieve-like contraptions to sifter plankton. The diameter of these filters are only 2-3 millimeters, prevent anything besides water and also smaller food particles from getting out of.
Virtually any organic material that's trapped between the gill filters is ingested right after. To the human viewpoint, the idea of filter-feeding seems somewhat difficult. You will probably find it tough to comprehend utilizing your mouth like a sponge filter as well as swallowing the dirt which builds up within the filter. Despite the fact that whale sharks are really well experienced when it comes to filter-feeding, the problem associated with it isn't lost for them. Oftentimes, the whale sharks are reported coughing as they are not able to swallow all the food particles stuck in their gill filters. Soon enough, the remaining particles there build up and also obstruct the filters, making it hard to eat without the need of coughing and, perhaps, choking.
These whale sharks feed actively. Contrary to many other species of sharks, or fishes as an example, whale sharks almost never stop eating. On the grounds that filter-feeding also doesn't need them to aquire for food, whale sharks may easily gulp in water no matter if they're resting in stationary position.
Various Other Filter-feeder Sharks
The basking shark as well as megamouth shark are among the shark species that filter-feeders. The basking shark doesn't filter-feed the manner in which whale sharks do. As an alternative to gulping and also expelling water thru their gills, basking sharks basically "basks," hence forcing the water to circulate by using their gills. The food particles are in that case accumulated and also swallowed.
The truth is, whale sharks are varies greatly from what you firstly suspected them to be. Their teeth serve no purpose as they are filter-feeders; not to mention they do not have big pointy teeth.
